System and method for policing spectrum usage
Transferring spectrum use rights may include ascertaining information regarding available spectrum for use in wireless communications. A request for spectrum use from a spectrum user system may be matched with available spectrum. A spectrum certificate may be issued to the spectrum user system, where the spectrum certificate contains at least one spectrum-related variable under which the spectrum user system is to engage in wireless communications.
1. A method of policing use of spectrum for wireless communications, comprising:
monitoring spectrum use in a geographic area to generate spectrum use data;
analyzing the spectrum use data to identify operation of a wireless radio system that is not compliant with a combination of a time window, a frequency-based spectral mask, a geography-based emission mask and a transmitted power limit of a spectrum certificate that is issued to the wireless radio system, the spectrum certificate being a data object that electronically binds the wireless radio system to carry out wireless communications in accordance with the frequency-based spectral mask, the geography-based emission mask and the transmitted power limit during the time window, the time window specifying when the spectrum certificate is valid and the wireless communications carried out in an environment with other wireless radio systems that conduct wireless communications in accordance with respective spectrum certificates, the wireless radio systems comprising a dynamically changing group of spectrum users having diverse spectrum needs, and the spectrum certificate availing part of a pool of available spectrum to the wireless radio system, the pool of available spectrum from plural spectrum holders each having authority to release use of the spectrum contributed to pool to another entity and the available spectrum in the pool dynamically changing over time as spectrum becomes available from the spectrum holders, as spectrum is no longer available for use by the spectrum users and as spectrum is allocated for use by the spectrum users in the spectrum certificates; and
generating a violation alarm corresponding to the identified wireless radio system operation.
2. The method of claim 1 , wherein the violation alarm includes an instruction to cease wireless communication within frequency variables associated with the frequency-based spectral mask.
3. The method of claim 1 , wherein the violation alarm includes an instruction to take remedial action so that the wireless communications comply with the spectrum certificate.
4. The method of claim 1 , wherein the violation alarm is transmitted to a broker system that issued the spectrum certificate to the wireless radio system.
5. The method of claim 1 , wherein the violation alarm is transmitted to the wireless radio system.
6. The method of claim 1 , wherein the spectrum use data is generated by deployed sensors.
7. The method of claim 6 , wherein the sensors are deployed to monitor spectrum usage at a perimeter of a geographic area.
8. The method of claim 7 , wherein the perimeter of the geographic area corresponds to a boundary of a geographic coverage area of a group of radio devices that operate in accordance with the spectrum certificate.
9. A system for policing use of spectrum for wireless communications, comprising a computer-implemented policing device that analyzes spectrum use data to identify operation of a wireless radio system that is not compliant with a combination of a time window, a frequency-based spectral mask, a geography-based emission mask and a transmitted power limit of a spectrum certificate that is issued to the wireless radio system and generates an alarm corresponding to the identified wireless radio system operation, and wherein the spectrum certificate is a data object that electronically binds the wireless radio system to carry out wireless communication in accordance with the time window, the frequency-based spectral mask, the geography-based emission mask and the transmitted power limit specified in the spectrum certificate, the time window specifying when the spectrum certificate is valid and the wireless communications carried out in an environment with other wireless radio systems that conduct wireless communications in accordance with respective spectrum certificates, the wireless radio systems comprising a dynamically changing group of spectrum users having diverse spectrum needs, and the spectrum certificate availing part of a pool of available spectrum to the wireless radio system, the pool of available spectrum is from plural spectrum holders each having authority to release use of the spectrum contributed to pool to another entity and the available spectrum in the pool dynamically changing over time as spectrum becomes available from the spectrum holders, as spectrum is no longer available for use by the spectrum users and as spectrum is allocated for use by the spectrum users in the spectrum certificates.
10. The system of claim 9 , wherein the violation alarm includes an instruction to cease wireless communication within frequency variables associated with the frequency-based spectral mask.
11. The system of claim 9 , wherein the violation alarm includes an instruction to take remedial action so that the wireless communications comply with the spectrum certificate.
12. The system of claim 9 , wherein the violation alarm is transmitted to a broker system that issued the spectrum certificate to the wireless radio system.
13. The system of claim 9 , wherein the violation alarm is transmitted to the wireless radio system.
14. The system of claim 9 , further comprising a plurality of deployed sensors that monitor spectrum use in a geographic area to generate the spectrum use data.
15. The system of claim 14 , wherein the sensors are deployed to monitor spectrum usage at a perimeter of the geographic area.
16. The system of claim 15 , wherein the perimeter of the geographic area corresponds to a boundary of a geographic coverage area of a group of radio devices that operate in accordance with the spectrum certificate.
